I pulled in all the tracing related patches (1-18) and pushed it to my repo: git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace.git ring-buffer/for-next It's based on top of v7.0-rc3. I'm not going to rebase that branch, although I may built on top of it, but for now, feel free to merge it into the arm tree and put the rest of the patches on top of it. -- Steve
